There exists an objective reality but we don't experience it directly. We take a tiny fraction of the information available and create our own realities from this. Nothing exists in the way you think it exists.
But Melkor made an excellent point earlier about who's to say which reality is real? all perceptions and points of view are as valid as each other.
If two people listen to a song and one of them loves it and one hates it. Who's right? they both are? love and hate are entirely creations of perception. They don't exist outside of our bodies. Whats really happening is the air is vibrating creating interference patterns which is translated into something ENTIRELY different to how it started by our brains. whether it's sounds good or not can never be said to be true or false.
Sound doesn't exist. colour doesn't exist. hot doesn't exist. cold doesn't exist. At least they don't outside of our perception. We are interference pattern detectors. nothing more. Every experience we have is an invention.
BUT. and this is a big fat BUT. how can we ever know that anything other than our perceptions exist? How do we know there exists an objective reality?
It may well be that we create our own realities. New developments and theories are beginning to suggest that there may not be an objective reality after all.
It's all rather confusing and to be honest, terrifying.
To sum up. we are real. But what you experience as reality isn't necessarily the final word. someone else may have a differnet view of reality which is just as valid
